Have you tried to search on EFI lives website for the info? Have you tried to book something up and see if it will work? If you guys can't find your answers, I guess you are going to have to do the work or leave it be. Isspro uses 5volt sensors, which is what you need, and a couple of us have told you that they last. I guess you need to figure out how to wire them in and scale the external sensor part correctly.
